SPECIFICATION forming part of Letters Patent No. 783,499, dated February 28, 1905.

Application fiied April 18, 1904. Serial No. 203,554.

To (Ml Hf/ton], (if; HM/gl conceit 1,:

Be it known that l, Fnnp H. IfiAILEY', o1 Leominster, in the county of Worcester and State of Massachusetts, have invented certain new and useful :lmprovemients in l-ittachments for Fire-Extinguishers; and i do hereby declare that the following is a full, clear, and exact description of the same.

This invention relates to lire-extinguishers, and particularly to that class in which a receptacle is overturned in order to cause a commingling of the charging agent with the liquid contained in the receptacle.

An object of this invention is to provide a lii'eextinguisher suitably suspended and held against action through the medium of a iusi ble retaining device, which being destroyed by heat occasioned by a lire will release the receptacle and cause a discharge of the liquid contained therein.

Furthermore, an object of the invention is to provide novel means whereby the fusible retaining device is utilized, making this inven tion applicable to this class of extinguisher-s now in use.

Furthermore, an object of this invention is to provide novel means for utilizing the overturning or partial rotationof the receptacle as a means for causing an alarm to be sounded when the receptacle is released.

Finally, an object of the invention is to provide an extinguisher oi? the character noted which will possess advantages in ei'liciency and durability proving comparatively inexpensive to manufacture and maintain.

iVith the foregoing and other objects in view the invention consists in the details of construction and in the arrangement and combination of parts to be hereinafter more fully set forth and specifically claimed.

In describing the invention in detail reference will be had to the accompanying drawings, forming part of this specification, where in like characters denote corresponding parts throughout the several views, in which-- Figure 1 is a view in elevation illustrating a receptacle suitably suspended and held in its inoperative position through the medium of the fusible coupling. Fig. 2 is a perspective view of the attaclnnent capable of being 1 applied to extinguishers now in common use.

the receptacle, the said trunnions being engaged by the hanger 3, having holes a for the reception of the trunnions. The hanger 3 has a yoke-like structure having a horizontallydisposed member and two depending members in which the trunnions are journaled. The portion 5 of the hanger extends a distance below the opposite member and terminates approximately on line with the bottom of the receptacle when said receptacle is standing upright. The arm 6 is slidable in a loop or keeper 7, arranged on the bottom of the receptacle, the said. arm having its end bent at an angle to the arm proper as shown at 8, the said extension being placed to lie parallel with thelower portion of the member A. retaining-band A, 01 fusible material, is slidable on the lower portion of the member 5 and is adapted to engage the end 8 of the arm (3, as shown in Fig. 1, whereby rotation oi. the receptacle is prevented so long as the band A remains intact.

The hanger is suspended from the ceiling or from any other suitable object and is attached thereto by means of screws a, which are run through apertures a in the horizontal portion of the said hanger. WV hen the parts are assembled in the relation shown in Fig. l and stationed at a place where there is danger of lire, should a lire occur the band, A will be destroyed when the heat has reached a prede termined temperatiire, thus allowing the trunnions of the receptacle to rotate and causing the said receptacle to upset, bringing the perforated head B down and permitting the contents of the receptacle to be sprinkled over the surface of the floor. Owing to the construction of the sprinkler there will be considerable divergence of the spray. As a further means for safeguarding the promises I utilize, in connection with the receptacle and the hanger, a signaling device whereby when the receptacle upsets an alarm is sounded by means of a contact C, here shown in the form of a small bracket attached to the side of the receptacle, which is positioned thereon to contact with a push-button D or other device for closing the electric current, which may flow over the conductorE to any suitable alarm. (Not shown.) As it is not my purpose to be limited to any particular alarm system or means for causing the signal to be given, the said alarm need not, itis thought, be described in detail.

The construction,operation, and advantages will, it is thought, be understood from the foregoing description, it being noted that various changes may be resorted to in the proportions and details of construction for successfully carrying the invention into practice without departing from the scope thereof.

Having fully described the invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a fire-extinguishing device, a receptacle, trunnions on the receptacle, a yoke in which the trunnions are mounted, an extension on one of arms of the yoke, a keeper on the bottom of the receptacle, an-arm slidable in the keeper, and a fusible connection between the extension of the yoke and the slidable arm.

2. In a fire-extinguishing device, a yoke, securing means on the yoke, a receptacle pivoted between the arms of the yoke, an extension on one of the arms of the yoke, an arm slidabl y secured to the bottom of the receptacle, one end of the arm being turned upward a portion of its length parallel With the extension of the yoke, and afusible slide on the extension adapted to embrace the upturned portion of the arm.

3. In a fire-extinguishing device, a yoke, a receptacle pivoted therein, a sliding arm on the bottom of the receptacle, a fusible connection between said sliding arm and one of the arms of the yoke below the pivotal point of the receptacle and a signal means carried by the yoke above the pivotal point of the receptacle.
